Question

나는 타이머와 TimerTask를 작성을 시도하지만 그것이 작동하는 :(

"당신의 포스트 코드 섹션을 설명하는 많은 컨텍스트가없는 얻을 수 없습니다 설명하시기 바랍니다 .? 시나리오 더 명확하게 "

오류

Answer 1

당신은 당신의 TimerTask 변수 tmtCheat, 따라서 NullPointerException 초기화되지 않습니다.

tmtCheat이라는 메서드를 Timer에 실행하려면 익명 클래스를 사용하거나 을 만들 수 있습니다.

timCheat.schedule(new TimerTask() { 
    public void run() { 
    // your code 
    } 
}, 500);
